Title: Negative pressure floating head slider
Inventor: TAGAWA NORIO
IPC: G11B21/21
Filed: 1986-02-17
Abstract: PURPOSE:To attain the extremely stable floating characteristics by providing a recessed groove part containing its closed circumference to a positive pressure generating surface. CONSTITUTION:A recessed groove 4a is formed on a positive pressure generating surface 2a. Thus the pressure is approximately equal to or less than the atmospheric pressure at the part of the groove 4a. While the area between the termination of the groove 4a and the trailing edge part of a slider serve as a positive step bearing and therefore the wedge effect is improved more. As a result, the reduction of the positive load capacity is minimized even though a lubricant fluid flows into the slider with a yawing angle. That is, the wedge effect of the slider is increased owing to the groove 4a formed on a pair of positive pressure generating surfaces. This suppresses greatly the positive pressure drop caused by the yawing angle and reduces greatly the reduction of the floating amount due to the yawing angle.
